Program Design & Testing Document for Final Program Lyell C Read Solution

This problem/assignment is asking me to construct a C++ program that:




Does not segfault



Compiles on FLIP



Does not leak memory



Allows the user to play ‘Escape from CS162’ - a maze game.



Checks arguments and plays from a map in a text file.



Uses the required classes, inheritance and polymorphism (below).



This program:



Allows the user to choose where to move, and only permits this move if there is not an enemy there.



Manages the “special events” related to TAs and Instructors, as well as ladders, start.



Moves the TA’s randomly, and keeps track of their level of appeased-ness



Manages the player’s programming skills



Manages encounters with TA’s



Resets level or game on certain failures (see README.md)



Asks the user if they want to play again.



I assume



The text file will be laid out per spec, as that will not be checked.



The user has knowledge of the game.


Classes/ Inheritance Structure




Understanding the Problem








As described in the requirements, the problem asks me to create a program that can play a nice game of ‘Escape from CS162’ using classes and inheritance and polymorphism. The game will be neatly organized, and follow the typical rules of the game listed in README.md, on GitHub. The class structure and member functions for this game are listed above.
